Here's my addition. I hope to get my M40 finished this year. I have all original stock, barrel, scope and mounting hardware.
About the swivels. Do we have any idea as to where we can get the front swivel escutcheon? And what is the thread size/pattern of the swivel/escutcheon? Must be a Remington part. Wichitas got the contract in 70.
We've got photos of the M40's short(ened) bolt shroud, but what is the exact length of this 'short' bolt shroud on the M40, measured from the shoulder/flange which butts against the receiver, to the rear edge?
Thanks!
Bolt shroud on mine is .885"

I thought it deserved to be full-sized, for those that keep photo reference files:

Observations:
Notice how some of the parts, i.e., tactical post, optic lens housing retaining ring and set screw in the power knob have a 'polished blue' color?
Q. for totenkpof:
In mint/unissued condition, are the color variations that we see in your photo, actual variations or, just due to photographing the piece?
My question arises from looking at the M40 in the NRA museum, which by all appearances, shows similar variations.
Thanks!
Cool. I have two NOS sets. I wonder if liquid sandpaper will take the gloss off.

You guys might be right about the aluminum floorplate. I dont have the Senichs book.
I will add something to the part about the M40A1. The Winchester 70 floorplate latch mechanism is outside the trigger guard, which makes it harder to accidentaly engage the mechanism and drops ammo. Apparently, the snipers didnt like the M40 at first, and asked that the M70 floorplate be used on the 'upgraded M40' which became the M40A1.
It has nothing to do with Remington. Most M40A1 were upgraded from M40. They came in the shop with the Remington floorplates. The armorers at Quantico simply tossed away the Remington units, replaced it with Winchester's, and installed it in the already inletted stocks specially prepared and inletted by McMillan.
The Remington contract was to supply the army with a bunch of Rem 700. Was Remington contacted about a steel floorplate? I dont know. And dont think so. Maybe. Do we have a proof of that somewhere? If yes, than we have solid facts to backup the theory about the aluminum floorplate.
I think I was bidding against you but stopped once someone else listed a pair of NOS stil in the wrap and sealed
Dear M40 Build Guide Thread,
You are the best and worst thing to happen to me.

Question(s):
2. I have a sight base that has the look, but isn't period correct. Where do ya'll find the best sources for these?
5. Buttplate Screws: One member said he thinks they're off a 740, can any substantiate that? They do look correct to me and I think the guy is right, just looking for further affirmation.
6. Clipslotting:
Who can do this?
Is it necessary?
7. Parkerizing: Who can do this? I've seen some people think the green tint of because of the oil they put on these rifles. Would parking the barelled action and dunking it in cosmoline and bombarding it with UV light work? I'm thinking along the lines of how Garands got their green color (maybe.) It might be a long shot, but I talked to a guy who swore by it.
JStill waiting on my stock.... Silver Hill has told me "We're making 12 right now, its shpping Friday" for the last 3 weeks. Not sure what's going on there.... I told him only ordered 1, not 12...![]()
Ha, I was told the same thing when I ordered one 2 weeks ago. How long did it take you to get your stock?
... Hours and hours of sanding, pillar bedded it, and it's a bit off for being sold as a "95% inletted stock". I would say I got a 75% inletted stock. But, the forend drifts to the left. Can't take anymore off without it being noticeable, so I have a tiny point of contact on the first inch of the stock against the barrel. Confirmed with a piece of thin cardboard. Found this out as I've been relieving it so much. The cutout for the floor plate and trigger guard is also off. I had to shift it over and fill it in.
Just curious... with all of this drifting and contacting and fitting and refitting and relieving and shifting, going on, to fit your barreled action, trigger group and bottom metal... to this stock... were you using 'inletting black' as an aide??
So here is the start of my attempt to make an accurate build
I have 90% stock and the brass insert, an old 60s 40X action with the short bolt shroud, double sear tombstone trigger, a NOS Redfield scope mount, a set of NOS Redfield 1" rings with the 4 slotted screws, the correct end plate, the only thing is that the barrel is a 22" Hart but it shoots a ragged hole so I might keep it a while till I decide to rebarrel. Still looking for that magic gen 1 scope to have re-anodized in order to make this a perfect period correct gen 1 M40 model. I went with the 40X since some have speculated that some of the first were 40Xs. The only other things beside the barrel that I need to correct, if I feel like doing so, is the internal magazine came with the cut aways and the bottom metal. I had it personalized and sitting around for a build for myself one day. So this is going to be the build I use it on. Any insight or corrections from you guys would be appreciated
Thanks

This should help in finding a correct Redfield scope for the period the M40 was introduced. I got this from a '66 catalog

4P CCH is a duplex reticle. 3 to 1 dot is a is a crosshair reticle with a dot at the intersection.
Jake:
Looking good. I have the same scope. I don't care about the reticle as well. The Marines didn't use the tombstone for shit.
Some 95% stock, huh? Mine was a mess, they actually sent me another one. But I pillar bedded the other, it's friggin' tight. And it came out nice. I'm gonna hold on to the other one and fit it when I'm ready... Or build another rifle. Lol. Lord know I got plenty of scopes!!Getting close. I got the stock yesterday from Silver Hill. I have probably 6 hours in it so far. The base I got from eBay for like $15 and the scope was another eBay find. It doesn't have the range finder reticle but I don't care. The rifle is a 2006ish PSS which has a 26" barrel but who cares.
